The South Korea international is expecting an ‘aggressive’ clash at Ibrox in the Champions League.
“The atmosphere in the stadium is totally different,” he said.
“You cannot compare it to a league game or others in the Champions League.
“It’s more aggressive on the pitch and the atmosphere in the stadium is really high. There is a lot more media attention as well.
“Nobody has to say anything, it is just a natural feeling that this is a different game.
“And it doesn’t only apply to the British players. It is equally special for the foreign ones as well.”
